If you happen to be an Xbox Insider on PC, Xbox has recently launched a brand-new feature called game hubs. This is also accessible to a subset of Xbox App users.
This is a new way to connect with your Xbox game library on the computer - allowing you to track progress, discover the latest content and add-ons, connect and compete with friends, get news updates from developers, easily track achievements, "and more".
"Game hubs were built on your feedback around depth, progression, and more ways to connect with your games...You can access game hubs from the Xbox App on PC — just click on the game in your library or the left sidebar."
It's apparently "just the beginning" - with another wave of updates "coming soon" which will also allow you to view local game captures and browse other games.
The hub even allows you to see data from 'HowLongToBeat' to get a better idea of playtime or compare runs to the rest of the community. You can learn more on Xbox Wire.
